Prophase Chromosome  pair up ! 1. Chromosomes thicken and shorten -become visible -2  chromatids  joined by a  centromere 2. Centrioles  move to the opposite sides of the nucleus 3. Nucleolus  disappears 4. Nuclear membrane disintegrate

M etaphase Chromosomes  meet in the middle ! 1. Chromosomes arrange at  equator  of cell 2. Become attached to  spindle fibres  by  centromeres 3. Homologous  chromosomes  do not associate

Unformatted text preview: Chromosomes get pulled apart 1. Spindle fibres contract pulling chromatids to the opposite poles of the cell T elophase Now there are two! 1. Chromosomes uncoil 2. Spindle fibres disintegrate 3. Centrioles replicate 4. Nucleur membrane forms 5. Cell divides Meiosis 4 daughter cells produced Each daughter cell has half the chromosomes of the parent 2 sets of cell division involved This powerpoint was kindly donated to www.worldofteaching.com http://www.worldofteaching.com is home to over a thousand powerpoints submitted by teachers.
